' OIL savnn.

v Application filed January 5, 192?. Serial Ho. 159,231.

My invention relates to improvements in oil savers tor storage tanks, and it consists in the combinations, constructions and arrange- ,ments herein described and claimed.

All storage tanks of the type now used in the field have their delivery outlets located at a considerable distance above the bottom or" the tankand are provided with normally closed. orainage outlets their bottoms. Sediment accumulates in the bottoms of the tanks and whenthe accumulation or" sediment in a tank is several inches below the level of the delivery outlet, it ordinarily is required that the tank be drained so as to pre vent sediment from passingfrom the tank with the oil through the delivery outlet. It

An object of the presentinvention is to save the oil in the bottom of the tank below the level of the delivery outlet by providing facilities for removing such oil from the tank without permitting the sediment in the bottom of the tank to mingle with the oil.

A further object of the invention is the provision of an oil saver which is adapted to be associated with the drain opening in the bottom of the tank and which includes vertically extensible removable liquid conducting means within the tank for drawing oil the oil below the delivery outlet gradually from the tank withoutappreciable disturbance of the sediment within the tank.

Other'objects and advantages or" the invention will be apparent. from the following description, considered in conjunction with the accompanying drawings, in which Figural is a vertical section through a storage tank equipped with an oil saver embodying the invention, l

Figure 6 is a tragmentaryview mainly in side elevation andpartly in vertical section, 65 showing the liquid conducting member of the modified form of oil saver in association with the drain outlet of a tank. 1

In Figure 1., the numeral 1 designates" an oil storage tank having a bottom 2 provided 79 with an opening 3 in which is, secured a short bushing l having a sealing flange 5 at its upper end resting onthe tankbottom 2, I The tankl is provided with a delivery: outlet-6 which is located a substantial distance above the bottom 2, When a considerable quantity of sediment has accumulated in the tank 1,

as ttor example, to the level indicated atl7, it ordinarily is'required thatthe tank be then is drawn off through the delivery outlet 6 until thelevel of oil within the tank is located approximately at 8 and it will be manifest that usuablc oil remains in the tank between the levels 7 and 8. Such oil can be removed without appreciable disturbance of the sediment below the-level? when the tank is equipped with an oil saver embody? ing the invention.

' n11 equipping the tank with an oil saver em- 90, bodying the invent1on, I may make use of a special reducer nipple 9 having external screw threads 10 at its lower end adapted for ,connectirm with a suitable section of a drain pipe, not showm and having external screw threads 11 at its upper end adapted to engage "with internal screw threads on the bushing 3. ihe upper end portion of the nipple 9 also is provided with internal screw threads 12- for a purpose to be presently ClQSCllbBd. lhe

body of the improved oil saver shown in Fig- 7 ures 1 and 2 comprises a tubular member 13 f having its'lower end portion provided with external screw threadsl l adapted to engage with the screw threads 12 on the upper end portion of the nipple 9 and having an out ivardly extending flange or head 15 at its The member 13 preferably is of sufficient length to extend vertically within the tank to the highest level to which sedi: 11a

section and showing a modified of the member 13 and has an inturned lug ment will be permitted to accumulate within the tank before the tank is drained. The member 13 is formed with a longitudinally extending guidegroove 16 in its outer wall having spaced lateral seats16 in a side wall thereof and with a rigid cross bar 17 at its upper end.

The body of the oil saver also comprises a vertically adjust-able tubular member 18 which has a close sliding lit with the flange 19 at; its lower. end in sliding contact with the groove 16 and engageable with the seats 16 selectively. and with shorter inturned lugs 19 cooperating with the body of the member 13,

. the lug 19 and the groove 16 and the flange I -wall of the member 13, respectively, after the i 15 to maintain the member 18in smooth sliding contact with the flange 15. The tubular member 18 has a pair of opposite inwardly extending stop lugs 20 at its upper end for en= gaging with the flange 15 to limit the clownward sliding movement of the member 18 on the'member 13. It, of course, will be understood that'the lugs 19 and 19 at the lower end of the member 18 are bent inwardly into engagement with thegroove and the outer member 18 has been placed on the member 13. The length of the member 18 is preferably nearly as great as that of the portion of the member 13 that is upstanding within the tank so that the lower end of the member 18 will be disposed close to the bottom of the tank when the lugs 20 rest on the flange 15 andthe member 18 is at the limit of its downward movement on the member 13. The member l8 is provided with a bail 21 at its upper end which is adapted to be engaged by a hook 22 at the lower end of an operating rod 23'which depends through an opening 24 in the top 25 of the tank 1 andl as a handle 26 at its upper end whereby it can be grasped and manipulated to adjust the member 18 vertically on the member 13 as desired. The portion of the operating rod 23, that extends through the opening 24 in the top of the tank has a vertical series of spaced transverse openings 27 with which .a supporting pin 28 may be engaged selectively, the length of the in Figure 1 so as to maintain the member 18 raised on the member 13 substantially to the level of the delivery outlet. lVhen the tank is to be drained and cleaned and the level of 'oil withinjthe tank is'at 8, the pin 28 is rebelow the level of the sediment in the tank.

The operating rod 23 then is manipulated to gradually lowerthe member 18 on the member13'from the position shown in Figure 1 until thelevel of the upper end of the member 18 is at the level of the sediment within the tank, the drain outlet or pipe for the tank first having been opened so that the oil will be drawn oil through the members .18 and 13 into the drain pipe as the member 18 is gradually andslowly lowered on the member '13. The member 18 will serve as a shield against the passage of sediment into the member 13 and the oil will be drawn ofii withoutany ap- Jreciable disturbance or a itation of the sedib ment in the tank and without any of such sediment being entrained with the oil. When all the usable oil has been removed from the tank in the manner just described, the pin 28 is disengaged from the operatingrod and the operating rod is manipulated to disengage the hook 22 from the'bail 21 andto place the hook 22 in engagement'with the cross bar 17 at the upper end of the member 13. The operating rod 23 then is 'manipulated to unscrew the member 13 from the nipple Sand the members 13 and 18 are raised as a unit within the tank as required to permit unobstructed passage of the sediment from thelower part of the,

tank through the nipple 9, after which the members 13 and 18 are lowered as a unit until the lower end of the member 13 is disposed at the upper end of the nipple 9 and the operating rod 23 then is manipulated to screw the member 13 to place in the upper end portion of the member 9.

In carrying out the invention 1n the form exhibited in Figures 5 and 6, I may omit the hereinbefore described member 13 and inlieu thereof I use a tube 30 which may be identical with the tube 13 except that the externally threaded lower end portion 31 of the tube 30 is shorter than the externally screw threaded lower end portion of the tube 13. The screw threaded lower end portion '31 0f the tube 30 is adapted to be screwed into a screw threaded counter bore 32 in the flange at-the upper'end of a rela tively heavy tubular base member 34. The tubular base member 34 is adapted to fit rather snugly into the opening 3 of the tank bottom 2 until a sealing gasket 35 on the" tubular base member 3 1 is compressed between the bottom 2 and the fiange33f The lower end portion of the tubular basement ber 34 maybe tapered externally as indicated at 36 both to facilitate the insertion of the tubular base member 34 in the opening 3 and to reduce the lower end port-ionof the tubular base member 34 in-size sufficiently to adapt it to enter the upper end of a drain lower end portion,

pipe 37 that is in screw threaded engagement with a connecting nipplev38 which depends from the tank bottom 2 in encircling relation to the opening 3. The flange 33 is relatively heavy,'as clearly shown in Figures 5 and6 and the flanged tubular base member 3% will remain by gravity in position to produce a fluid pipe joint between itself and the tank bottom 2whenthe tubular base member 34 is in the position shown in Figures 5 and 6 and particularly when a gasket 35 is dis-' posed between the flange 33 and the tank bottom 32.

It will be understood that the tubular member 18 is used with the member 30 in the same manner as with the tubular member 13. Y i

1 The operation of the form of the device exhibited in Figures 5 and 6 is identical in essential respects with the operation of the form of the device exhibited in Figure 1.

Obviously, the invention is susceptible of embodiment in forms other than those which are illustrated in thev accompanying drawings and I therefore consider such modifications and adaptations thereof as fairly fall within the scope of the appended claims.
